ALFRED B. BELL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO I-IALE AND KILBURN COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF DELAWARE.

Application ile March 23, 1915.

To all whom it may concern:

Be it known thatl, ALFRED B. BELL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Peni'isylvania, have invented certain new and useful Improvements in Hinges and Casings Thereiior, of which the following is a specification.

My invention relates particularly to the construction of hinge casings and the parts coacting therewith such as are adapted to be applied to the bottom edge of drop doors, which are adapted to swing downwardly and outwardly to open position. My invention relates to the character of construction disclosed in the patent of Robert B. Caverly and Alfred B. Bell, drop door hinges, No. 1,176,73-i, dated March '28, 1916. In the construction referred to, a hinge cover or casing is provided, preferably formed of sheet-metal, with-'flanges secured to the front of the range or frame member, the pivot pin ot' the hinge being supported in openings in the side walls of the casing, the pivot pin having arms integral therewith secured to a bottom corner of the door; An inwardly directed stop or lug is pro'- vided within the casing, serving as a stop to coact with a member onthe pivot pin having a projection which engages the stop member in the casing when the door is in open position, a spring also being provided within the casing to resist opening movement oi. the door. My invention constitutes an improvement upon the devices referred to in the means whereby the hinge casing is secured to the frame. I provide one of the flanges ci1 the hinge casing with a screwhole and one or more other flanges with slots therethrough so positioned and shaped as to permit engagement of the slot or slots with a headed pin or pins mounted in the frame, by a simple movement of the casing parallel to the frame to engage the pin or pins. I prefer to provide the screw-hole in the upper iiange of the casing. The slot referred to may be an open-ended slot formed in the edge portion of one of the flanges, or it may be a slot formed with the shape of a keyhole, having a comparatively wide, and a narrower portion, whereby the casing may be mounted by moving the same against the frame with the head of the pin referred to extending through the wider portion of the slot, and then moving the casingparallel Speccation of Letters Patent.

to the trame to engage the shank of the pin in the narrower portion of the slot. Or both the open-ended slot and the keyhole-shaped slot may be use in different iianges at the same time, this constituting my preferred construction. By these means, the hinge casing may be very easily and quickly mounted in position, and removed, with the necessity for securing or removing only a single screw or bolt for each hinge casing.

In order that a clearer understanding of my invention may be had, attention is hereby directed to the accompanying drawings forming part or' this speciication and showing certain embodiments of my invention. In the drawings, Figure 1 represents a partial front elevation of a door pivoted to a supporting frame by a pair of hinges, Fig. 2 represents, on an enlarged scale, one corner of the door and the hinge construction ooacting therewith, the hinge cover being shown in section, and the flanges of the hinge casing being of a different form from those shown in Fig. l, Fig. 3 is a transverse vertical section on line 3--3 of Fig. 2 and Fig. Ll is a transverse vertical section on line ll-4 of Fig. 1, on an enlarged scale.

The door 1 is pivoted adjacent its lower edge to the frame member 2, which may be the front sheet of a gas range. Hinge covers or casings 3, 3 are secured to the frame member adjacent the lower corners of the door, the hinge casings preferably being formed of sheet-metal pressed to the shape illustrated. The pivot members are preterably each formed with vertical and horizontal flanges t, 4l and 5, 5, secured to the side and bottom edges of the door 1. Each pivot member is provided with a pivot pin 6, integral therewith, having cylindrical portions rotatably mounted in the side-walls of the hinge casings as shown. Each pin 6 is also preferably provided with a squared portion 7 on which is mounted a disk 8 having a square hole therethrough, disk 8 having projection 9 thereon adapted to contact a lug 10 extending inwardly of the casing, to act as a stop and hold the door in lowered position. A spiral spring 11 is coiled about each pivot pin within its casing to resist the opening movement of the door, one end of the spring being secured in disk 8 and the other end of the spring being inserted in a hole in frame member 2 as Ashown in Fig. 4. The stop member 10 within the casing may be a separate piece bent to an angle and welded within the casing as shown in Fig. 3, or it may be formed intee gral with the casing, for example, by slitting the metal of the casing and pressing it inwardly to form a stop as shown at 10 in Fig. Ll.

1`he hinOe casing is preferably secured to the traine in the manner indicated in Figs. 1 and 4 in which the casing is provided with an upwardly extending flange 12 and a downwardly extending liange 13, above and below the body of the casing respectively, and a side fiange 14 extending` inwardly of the frame from a side of the casing. The top flange 12 is provided with a screw-hole through which a screw or bolt 15 may be passed and screwed into the frame 2.- The bottom l'lange 13 is illustrated as provided with the keyhole slot l'having a comparatively large opening at the bottom thereof vand a narrower slot extending thereinto at the upper part. The ange 111 is provided with a slot 17 formed in the lower edge thereof, slots 16 and 17 being adapted to engage headed pins 18 and 19, respectively, projecting outwardly from the frame 2. Vhen a hinge casing is to be mounted in position, it is only necessary to press the same against the front of thel frame with the head of pin 18 projecting through the large opening of keyhole slot 16, when the casing may be rocked into position to bring the slot 17 into line with headed pin 19. The casing is then pressed downwardly to cause pin 18 to engage within the narrow portion of the keyhole slot and pin 19 'to engage within the open-ended slot 17. The screw 15 may then be secured in place, the

hinge casing thusV being quickly and se-V curely positioned with the aid of only one removable screw or bolt.

In Figs. 2 and 3 is shown a modication in which the bottom slot 13 is omitted, the casing being positioned and secured only by the engagement of headed pin 19 in slot 17 of the side flange 14 and the screw or bolt 15 extending through flange 12. lt is obvious that slots of the character of the open-ended slot 17 or the keyhole slot 16 may be used in either one or both of several flanges, or that slots 16 and 17 may be interchanged, or that slots of diierent coniiguration may be used, operating in the saine manner as that described. y

Having now particularly described my invention, what I claim and desire to protect by Letters Patent is as follows In a hinge construction, a hinge casing having an inclosed portion adapted to receive a pivot pin and spring, with side walls pierced to receive the pin, and upper, lower and side iianges, one of the saine having a screw-hole therethrough, another having a keyhole-shaped slot therethrough, and a third having an open-ended slot in an edge thereof, substantially as set forth.

This specification signed and witnessed this 19th day of March, 1915.
